Hi @Cao Van Luc
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
The first thing I suggest is to check the logs of your VM inside the var log azure folder. These logs can provide more specific error information and help identify trends. If you find expansion errors, that will give us a better idea of the next step.
If the logs don’t show anything obvious, I recommend uninstalling and reinstalling the extension via the Azure portal or CLI. Sometimes a new installation can solve problems that occur during the initial setup. Also, be sure to use the latest version of the Sute Recovery extension, as older versions may not support Ubuntu 22.04 at all. If the problem persists, you may want to check if your VM has enough resources (such as disk space, memory, or CPU) for the expansion to work properly.
If you have any further queries, do let us know
